Polyurethane foaming agents ndi chopangidwa cha mtanda-kuphatikiza feteleza waukadaulo wa aerosol ndi ukadaulo wa thovu la polyurethane. Amapangidwa mumitundu yonse iwiri ya chubu ndi mfuti, kuwonetsa siponji-ngati momwe. Zopangira thovu zomwe zimagwiritsidwa ntchito popanga mapulasitiki a thovu a microporous nthawi zambiri amagawidwa m'magulu awiri: thupi ndi mankhwala. Kugawika kumeneku kumatengera ngati kupangidwa kwa gasi ndizochitika zakuthupi (ie, kusinthasintha kapena kutsika) kapena njira yamankhwala (ie, kuwonongeka kwa zinthu zamagulu kapena zochitika zina).
Polyurethane foaming agent, yomwe imadziwikanso kuti single-component polyurethane foam sealant, nthawi zambiri imatchedwa kuti foaming agent, foaming adhesive, kapena PU sealant. Mawu achingerezi akuti PU FOAM adachokera ku-kuphatikiza ukadaulo wa aerosol ndi ukadaulo wa thovu la polyurethane. Ndi chinthu chapadera cha polyurethane chomwe chili ndi polyurethane prepolymer, chopangira thovu, chothandizira, ndi zinthu zina mu chitini cha aerosol. Zinthuzo zikapopera kuchokera ku aerosol can, zinthu za thovu la polyurethane zimakula mwachangu ndikuchitapo kanthu ndi chinyezi mumlengalenga kapena gawo lapansi lomwe limakumana nalo ndikupanga thovu. Iwo ali osiyanasiyana ntchito. Ili ndi maubwino a-kutulutsa thovu, kufutukuka kwambiri komanso kuchepa pang'ono. Chithovucho chimakhala ndi mphamvu zabwino komanso kumamatira kwakukulu. Pambuyo pochiritsa, chithovucho chimakhala ndi zotsatira zingapo monga kudzaza mipata, kulumikiza, kusindikiza, kutsekereza kutentha komanso kuyamwa kwamawu. Ndi zomangira zomwe sizingawononge chilengedwe komanso zopulumutsa mphamvu{11}zosavuta kugwiritsa ntchito. Ikhoza kugwiritsidwa ntchito kusindikiza ndi plugging kutayikira, kudzaza mipata ndi kukonza ndi kumangiriza, kutsekereza kutentha ndi kutulutsa mawu. Ndikoyenera makamaka kusindikiza ndi plugging kutayikira ndi kutsekereza madzi pakati pa pulasitiki zitsulo kapena aluminiyamu aloyi zitseko ndi mazenera ndi makoma.
